Risk of retinal diseases in patients with psoriasis: A population-based cohort study in Taiwan

Propensity-Matched Analysis of the Risk of Age-Related Macular Degeneration with Systemic Immune-Mediated Inflammatory Disease

PURPOSE

The pathogenesis of age-related macular degeneration (AMD) involves aberrant complement activation and is a leading cause of vision loss worldwide. Complement aberrations are also implicated in many systemic immune-mediated inflammatory diseases (IMIDs), but the relationship between AMD and these conditions remains undescribed. The aim of this study is to first assess the association between AMD and IMIDs, and then assess the risk of AMD in patients with specific IMIDs associated with AMD.

DESIGN

Cross-sectional study and cohort study.

SUBJECTS AND CONTROLS

Patients with AMD were compared with control patients with cataracts and no AMD to ensure evaluation by an ophthalmologist. Patients with IMIDs were compared with patients without IMIDs but with cataracts.

METHODS

This study used deidentified data from a national database (2006-2023), using International Classification of Diseases 10 codes to select for IMIDs. Propensity score matching was based on patients on age, sex, race, ethnicity, and smoking. Odds ratios were generated for IMIDs and compared between AMD and control patients. For IMIDs associated with AMD, the risk of AMD in patients with the IMID versus patients without IMIDs was determined utilizing a cohort study design.

MAIN OUTCOME MEASURES

Odds ratio of IMID, risk ratios (RRs), and 95% confidence intervals (CIs) of AMD diagnosis, given an IMID.

RESULTS

After propensity score matching, AMD and control cohorts (n = 217 197 each) had a mean ± standard deviation age of 74.7 ± 10.4 years, were 56% female, and 9% of patients smoked. Age-related macular degeneration showed associations with systemic lupus erythematosus (SLE), Crohn's disease, ulcerative colitis, rheumatoid arthritis (RA), psoriasis, sarcoidosis, scleroderma, giant cell arteritis, and vasculitis. Cohorts for each positively associated IMID were created and matched to control cohorts with no IMID history. Patients with RA (RR, 1.40; 95% CI, 1.30-1.49), SLE (RR, 1.73; 95% CI, 1.37-2.18), Crohn's disease (RR, 1.42; 95% CI, 1.20-1.71), ulcerative colitis (RR, 1.45; 95% CI, 1.29-1.63), psoriasis (RR, 1.48; 95% CI, 1.37-1.60), vasculitis (RR, 1.48; 95% CI, 1.33-1.64), scleroderma (RR, 1.65; 95% CI, 1.35-2.02), and sarcoidosis (RR, 1.42; 95% CI, 1.24-1.62) showed a higher risk of developing AMD compared with controls.

CONCLUSIONS

The results suggest that there is an increased risk of developing AMD in patients with RA, SLE, Crohn's disease, ulcerative colitis, psoriasis, vasculitis, scleroderma, and sarcoidosis compared with patients with no IMIDs.

Psoriasis Comorbidities and Their Treatment Impact

Psoriasis, a systemic inflammatory disease classically presenting with cutaneous lesions, has significant involvement in other organ systems. This article explores the prevalence, clinical manifestations, screening mechanisms, and laboratory testing by which to evaluate these comorbidities. Treatment approach for these comorbidities must combine patient preference with established treatment algorithms while recognizing innovative therapeutics currently under development.

PSORIASIS INCREASES RETINAL VEIN OCCLUSION RISK IN DIABETIC PATIENTS: A Nationwide Population-Based Study

PURPOSE

The objective of this research was to explore how psoriasis is linked to the occurrence of retinal vein occlusion (RVO) in diabetic population.

METHODS

This was a retrospective, nationwide, population-based cohort study that examined medical records from January 2009 to December 2012. The study focused on patients ≥20 years of age who had been diagnosed with Type 2 diabetes mellitus (DM). The authors compared the incidence rate of RVO between a group of patients with psoriasis and a group of patients without psoriasis until December 2018 in all subjects.

RESULTS

Of the 2,745,689 Type 2 DM patients, 23,725 patients were classified in the psoriasis group and the rest of the 2,547,121 individuals in the control group. A total of 497 RVO cases occurred in the psoriasis group (3.14/1,000 person-years) and 42,388 RVO cases in the control group (2.44/1,000 person-years). According to multivariable Cox proportional hazard models, individuals with psoriasis had a significantly greater risk of developing RVO compared with control subjects (hazard ratio: 1.216, 95% confidence interval: 1.11-1.33) after adjustments for covariates.

CONCLUSION

This study demonstrated that psoriasis was an independent risk factor for developing RVO in DM patients. Therefore, physicians need to be vigilant for the occurrence of RVO in DM patients who also have psoriasis.

Association between Retinal Vein Occlusion and Psoriasis in Korea: A Nationwide Population-based Prospective Cohort Study

Psoriasis is a chronic inflammatory skin disease imparting increased risk of cardiovascular diseases. Until now, few studies have reported an increased incidence of ophthalmological retinal vasculopathy in individuals with psoriasis. This study aimed to investigate the association between psoriasis and retinal vein occlusion in the Korean population. Data collected by the National Health Insurance Service between 2009 and 2015 in Korea were analysed. Participants who underwent national health examinations from 2009 to 2012 were enrolled in this study and were divided into either the psoriasis group (n = 3,088) or the control group (n = 465,205). All occurrences of retinal vein occlusion were observed, and the incidence rate of retinal vein occlusion was compared between the psoriasis and control groups. A Cox proportional hazards regression analysis was used to assess the association between psoriasis and newly developed retinal vein occlusion. During a mean 4.37-year follow-up period, 2,034 patients developed retinal vein occlusion. According to multivariable Cox proportional hazard models, individuals with psoriasis had a significantly higher risk of retinal vein occlusion compared with controls (hazard ratio 1.72, 95% confidence interval 1.18–2.51) after adjustments for covariates. This study found that psoriasis was positively associated with retinal vein occlusion.

Epidemiology of Psoriasis and Comorbid Diseases: A Narrative Review

Psoriasis is a chronic autoimmune inflammatory disease that remains active for a long period, even for life in most patients. The impact of psoriasis on health is not only limited to the skin, but also influences multiple systems of the body, even mental health. With the increasing of literature on the association between psoriasis and extracutaneous systems, a better understanding of psoriasis as an autoimmune disease with systemic inflammation is created. Except for cardiometabolic diseases, gastrointestinal diseases, chronic kidney diseases, malignancy, and infections that have received much attention, the association between psoriasis and more systemic diseases, including the skin system, reproductive system, and oral and ocular systems has also been revealed, and mental health diseases draw more attention not just because of the negative mental and mood influence caused by skin lesions, but a common immune-inflammatory mechanism identified of the two systemic diseases. This review summarizes the epidemiological evidence supporting the association between psoriasis and important and/or newly reported systemic diseases in the past 5 years, and may help to comprehensively recognize the comorbidity burden related to psoriasis, further to improve the management of people with psoriasis.

Identifying and Treating Ocular Manifestations in Psoriasis

Psoriasis is a chronic immune-mediated inflammatory skin condition that commonly presents with red, thickened, and scaling plaques. Given the prominent cutaneous manifestations of psoriasis, more subtle ophthalmic findings of the disease may initially go undetected, with the potential for significant ocular morbidity. Associated ocular disease can involve nearly any structure of the eye, with the eyelids most commonly being affected, resulting in relatively common signs and symptoms of ocular surface discomfort. The presence of intraocular inflammation (i.e., uveitis) or retinal involvement carry a heightened risk of vision loss, and are often more difficult to diagnose outside of the ophthalmology clinic. Early detection and treatment of ocular disease can limit morbidity and are critical to the management of these patients, which requires coordination of care between dermatologists and ophthalmologists. The objective of this article was to review the most common ocular conditions that affect psoriatic patients, when to consider referral to an ophthalmologist, and to summarize the adverse ocular effects of current psoriasis treatments.

Association between alopecia areata and retinal diseases: A nationwide population-based cohort study

BACKGROUND

Growing evidence has revealed abnormalities in the retinal structures of patients with alopecia areata (AA). However, the relationship between AA and retinopathy remains unclear.

OBJECTIVE

To investigate the association between AA and retinal diseases.

METHODS

The study participants were recruited from the National Health Insurance Research Database in Taiwan. We included 9909 patients with AA and 99,090 matched controls to assess the risk of retinal diseases. A Cox regression model was used for all analyses.

RESULTS

Compared with the controls, patients with AA had an adjusted hazard ratio (aHR) of 3.10 (95% confidence interval [CI] 2.26-4.26) for retinal diseases. With respect to individual retinal diseases, Patients with AA had significantly higher risks of developing retinal detachment (aHR 3.98; 95% CI 2.00-7.95), retinal vascular occlusion (aHR 2.45; 95% CI 1.22-4.92), and retinopathy (aHR 3.24; 95% CI 2.19-4.81) than controls.

LIMITATIONS

This was a retrospective cohort study. Meanwhile, almost all the participating individuals were residents of Taiwan; therefore, the validity of our findings in other demographics remains unclear.

CONCLUSION

Patients with AA had a significantly higher risk of retinal disease than controls. Further studies are needed to clarify the pathophysiology of AA and retinal diseases.
